Quebec did not ice a team for the season. Quebec's players were dispersed by draft and Montreal chose Joe Hall, Joe Malone and Walter Mummery.[1]Georges Vezina led the league in goals against average of 4 per game and Joe Malone had an outstanding 44 goals in 20 games to lead the league in goals.

The team was forced to return to its former arena the Jubilee Rink after the Montreal Arena burned down on January 2, 1918. The rival Montreal Wanderers folded after the fire, leaving only three teams (Montreal, Ottawa and Toronto) to continue the season. The Wanderers' players were dispersed and the Canadiens picked up Billy Bell and Jack McDonald.

On January 28, 1918, when Canadiens visited Toronto, Toronto's Alf Skinner and Montreal's Joe Hall got into a stick-swinging duel. Both players received match penalties, $15 fines and were arrested by the Toronto Police for disorderly conduct, for which they received suspended sentences.

Wanderers defaulted scheduled games against the Canadiens (Jan. 2, 1918) and Toronto (Jan. 5, 1918), when their arena burned down. These appear as losses in the standings, but the games were not played.[2]

The Canadiens played the Torontos in a playoff to decided the league championship. In a two-game, total-goals series, Toronto won the first game 7–3 and Montreal won the second game 4–3. Toronto won the series 10–7 and proceeded to the Stanley Cup playoffs.

The deadline did expire, and the once-powerful team that had been known as the Little Men of Iron was thrown onto the scrap heap of hockey history. The Wanderers' scheduled games of January 2 and 5 were officially recorded in the standings as victories for their respective opponents, the Canadiens and Torontos.”
